摘要：

The dispersion of intrasubband plasmons and single particle excitations in a layered electron gas system is investigated by micro-Raman spectroscopy and grating coupler assisted Raman scattering. This techniques allow variable in-plane momentum transfer up to the maximum value possible in inelastic light scattering. Raman scattering from a lateral quantum wire superlattice revealed a strongly anisotropic plasmon dispersion. A quantitative description is obtained in the confined plasmon model.
